Types of Pumps Centrifugal Pumps Centrifugal pumps are the most common type of pump used in industrial and commercial settings. They work by converting rotational energy into kinetic energy to move fluids. The fluid enters through the pump’s center and is then accelerated by the impeller, which rotates at high speeds. As the fluid moves…

Carnot cycle Introduction: The Carnot cycle is a thermodynamic cycle that was introduced by French physicist Sadi Carnot in 1824. It is a theoretical model for a heat engine that operates between two heat reservoirs at different temperatures. This cycle is an idealized model of the heat engine, and it is used to describe the…

Introduction A venturi meter is a device used to measure the flow rate of a fluid in a pipe. It consists of a converging section, a throat section, and a diverging section. The fluid enters the converging section, where its velocity increases and its pressure decreases. The fluid then passes through the throat section, where…

Manometer Introduction: Manometers are devices that measure fluid pressure, typically using a column of liquid. They have a variety of applications, including in industrial processes, HVAC systems, and medical equipment. What is a manometer? A manometer is a device used to measure pressure. It consists of a U-shaped tube filled with a liquid, usually mercury,…

Bearings are mechanical devices that allow two surfaces to move relative to each other while minimizing friction and wear. Various types of bearings are available, each with unique features suited for specific purposes. 1. Ball Bearings:Â These are the most common type of bearings that use a spherical rolling element to reduce friction between two…
Nuts and bolts are two of the most commonly used fasteners in a wide variety of applications. They are used to hold two or more objects together or to attach objects to a surface. While they are both types of fasteners, there are some differences between nuts and bolts in terms of their design, function,…
Lathe machine parts:Â A lathe machine is a tool used to shape, cut, drill, or turn a workpiece by rotating it against a cutting tool. The machine is composed of several parts, including: Also, read Automobile Clutch Friction Materials
Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through low-amplitude, high-frequency vibrations of a tool against the material surface in the presence of fine abrasive particles. Ultrasonic vibration machining physically operates through the mechanism of microchip or erosion on the surface of the workpiece. As the abrasive…

Although iron and steel are the most common and important materials that we have to deal with, there are other metals used in the workshop that you will need to have some knowledge of. The main pure metals from the non-ferrous group that the reader will have to deal with are aluminium, copper, lead, tin…

All of the workshop engineer’s energy is directed towards some aspect of changing the shape of the metal, and we will now discuss the general issue of hot and cold working. Cold working means subjecting the metal to forces that cause it to undergo plastic deformation when it is below the lowest critical temperature (perlite…

The purposes of annealing are (1) To soften steel so it can be machined more easily (2) To relieve internal stresses that may have been caused by metalworking or uneven shrinkage in the casting. The process involves (A) Heat slowly to the required temperature (B) Holding at this temperature long enough to allow internal changes…
